Reactor bottle cap for brine shrimp hatchery — compact, easy-to-use cap that converts a standard soda or water bottle into an aerated hatchery. Key benefits - Simple setup: fits on any soda or water bottle to create a ready-made brine shrimp reactor without special equipment. - Controlled aeration and harvest: dual-port design lets you run an air pump on one side and release brine shrimp from the other, avoiding spills and reducing handling stress on nauplii. - Reliable compatibility: designed to accept standard tubing with the specified joint size for a secure connection. What it does - Reactor bottle caps to use on any soda/water bottle for a brine shrimp hatchery. - Trachea that can be connected with the joint is 4MM in inner diameter and 6MM in outer diameter. - Use one side for the air pump, and the other side to release the brine shrimp into a container. Important attributes - Function: converts ordinary bottles into small-scale brine shrimp reactors for hatching and short-term culture. - Compatibility: fits standard soda/water bottles and interfaces with tubing sized 4MM ID / 6MM OD at the joint. - Performance: enables continuous aeration and a separate outlet for harvest, simplifying feeding and transfer of live nauplii. Practical use scenarios - Home aquarium hobbyist: set up a low-cost hatchery on a kitchen bottle to produce fresh brine shrimp for feeding fry and small fish. - Classroom or educational lab: demonstrate life cycles and culturing methods using readily available bottles and an air pump; clean harvest via the release port. - Small-scale breeding or research: run multiple reactors in parallel to stagger hatches and harvest nauplii without disturbing ongoing cultures. What to expect - Easy integration with common air pumps and standard beverage bottles. - Clear separation of aeration and harvest functions to minimize culture disruption. - Straightforward handling for routine hatching, feeding, or classroom demonstrations.
